I use Amadeus Pro to post process audio books from the library and after I process several books, usually 7 to 10 files of 6 or more hours each, Amadeus will usually crash. A restart will bring up the crash recovery dialog and will require a force quit before it returns to regular operation.
I have also experienced Amadeus Pro losing the setting for sending sound to the headset I am using and sending the sound to the external speakers. This usually happens when I am about halfway through a book. Sometimes after one or 2 books have been completed.
Most of what I do is to chapterize the books, split according to markers so that I can combine them into an audiobook with chapters using AudioBookBinder.
I would dearly love to be able to save an iPod ready book with chapters directly from Amadeus Pro.
